which of these four amps for Wharfedale Elysian 4's?

The Yamaha A-S2200 will give you an excellent integrated. You will need only a streamer and DAC. I have used Denefrips Enya with mine and a Sonos Port, but Wiim Pro Plus or Bluesounf Node  (or any streamer) should do.

I have not heard the Ayre, but based on reputation and its ability to double ts wattage into 4 ohms, that would be my choice. It is going to be a nice system, plan for a real preamp, it is the heart of your system. 

thank you

I can likely acquire the matching preamp to those power amps listed at a later date, and in fact would like to do so

RME direct to power amp has been working out pretty well, I started doing this previously at the suggestion of a various members both here and on the RME

forums

the RME has also worked out connected to various integrated amps into their standard line level input

I would go with the Ayre,I believe it's the best out of all the amps on the list.

ok, bought the Ayre per the multiple recommendations

bought the Kinki also as seller gave me a good price on matching preamp

thought it would be nice to have both to get a comparison

I think im done here

thanks all
